Which OS and CPU pair is more reliable for 24/7 running of Grafana on local hardware

Planning to run Grafana and SQLite on (non-fast) local hardware.

Which OS and hardware is best for 24/7 operation? Aim for non-stop running 6 to 12 months without hangup.

CPU: choose between low-end AMD, Raspberry Pi 5 or Intel N100. May be 8GB or 16GB RAM

OS: choose between Ubuntu, Raspberry Pi OS or other Linux?
